Moviemakers producing a film about the U.S. special forces raid that killed Osama bin Laden are getting help from the Pentagon, but the Obama administration dismissed concerns on Wednesday that classified information has been divulged.

The film, focusing on one of President Barack Obama’s key successes in office, is due to be released in October 2012, less than a month before the election in which the Democrat is seeking a second term.

Republican Peter King, chairman of the House of Representatives Homeland Security Committee, called on Tuesday for an investigation into contacts between the administration and the filmmakers. King questioned whether special operations methods had been compromised.
